Node.js Nodejs：按顺序递增foreach循环内的序列号

我一直在做一个MEAN stack项目，现在还没有使用Angular。我被困在一个点上，我尝试了这么多的事情来摆脱，但没有选择的工作。我一直在使用偶数发射器来处理Node.js的异步特性，以便按顺序执行逻辑验证。我的代码是

            flowController.on('12', function (combinedArray, finalPickSubListInsertArray) {

            var dummyObject = [];

            async.forEach(finalPickSubListInsertArray, function (element, callback) {

                locationStoreModel.findOne({'_id': element.locationStoreId, 'activeStatus': 1}, function (err, locationRow) {

                    if (err) {

                        flowController.emit('ERROR', {message: "Location data missing! Records tampered/removed from system", status: 'error', statusCode: '404'});
                    } else {

                        pickSubListModel.find({'pickListId': pickListId, 'activeStatus': 1}).sort({'sequence': -1}).exec(function (err, pickSubListRow) {

                            if (err) {

                                res.json({message: 'Internal Error fetching pick sublists!', status: 'error', statusCode: '500'});
                            } else {

                                var sequence = (pickSubListRow.length == 0) ? 1 : (pickSubListRow[0].sequence + (dummyObject.length + 1));

                                var newPickSubList = new pickSubListModel();

                                newPickSubList.pickListId = pickListId;
                                newPickSubList.itemCode = itemCode;
                                newPickSubList.itemStoreId = element.itemStore;
                                newPickSubList.itemDescription = itemDescription;
                                newPickSubList.requiredQuantity = requiredQuantity;

                                newPickSubList.sequence = sequence;
                                newPickSubList.createdBy = createdBy;
                                newPickSubList.timeCreated = timeInInteger;

                                newPickSubList.save(function (err, insertedRecordDetails) {
                                    if (err) {

                                        res.json({message: 'INTERNAL SERVER ERROR, UNKNOWN SERVER ERROR HAS OCCURRED', status: 'error', statusCode: '500'});
                                    } else {

                                        pickListModel.update(
                                                {'_id': pickListId},
                                                {'$addToSet': {'pickSubLists': insertedRecordDetails._id.toString()}},
                                                function (err) {

                                                    if (err) {
                                                        // error while adding records
                                                        res.json({message: "Unable to make update! Try again after some time.", status: 'error', statusCode: '500'});
                                                    } else {

                                                        dummyObject.push({process: 'done'});

                                                        callback();
                                                    }
                                                });
                                    }
                                });
                            }
                        });
                    }
                });
            }, function (err) {

                if (err) {

                    res.json({message: 'Unable to create pick-sublist! Try again later.', status: 'error', statusCode: '304'});
                } else {

                    res.json({message: 'New Pick-Sublist added into the system!', status: 'success', statusCode: '200'});
                }
            });
        });

在这里，我尝试将连续记录插入MongoDB集合，插入的每条记录都将获得递增的序列号我的问题是，当我进入foreach时，记录会被插入到集合中，但所有记录都会以增量方式获得相同的序列号。

我做了一系列的11次验证，然后到达事件发射器12，现在是将记录插入数据库的时候了。我的处境就像我吃掉了整头大象，只剩下尾巴&那条尾巴让我难以消化

如果您对如何满足这一需求有任何建议，我们将不胜感激……

您是否尝试了

async.eachSeries

使其自然同步？不，亲爱的……好的，让我看看它是多么神奇！它就像一个符咒…谢谢
